Panspermia on the Moons of Jupiter? New Study Finds It Possible, While Another Finds Evidence of Clay-Like Minerals on Europa

New studies strengthen the case for the possibility of life, carried by asteroids or comets on places like Europa. Image Credit: NASA/JPL/Ted Stryk.

Even though Mars receives most of the spotlight today when it comes to searching for places in the Solar System—besides Earth—where life might have arisen, there are many in the scientific [...]

Curiosity Determines Ancient Lake Was Habitable, While MRO Suggests Water Might Still Flow on Mars

This week, NASA released some very interesting findings regarding water on Mars, from both the agency’s Curiosity rover and the Mars Reconnaissance Orbiter (MRO). It has been known for years that Mars did indeed have liquid [...]

MAVEN Begins 490-Million-Mile Journey to Reveal Secrets About Mars' Ancient History

After a decade of work from a team spread across the country, NASA’s MAVEN spacecraft is on its way to Mars, beginning [...]

Cassini Reveals Saturn in Stunning 400,000-Mile-Wide Natural-Color Panoramic Mosaic

NASA’s Cassini spacecraft took this natural-color portrait on July 19, 2013, which is the first image to show Saturn, its moons, and rings, plus Earth, Venus, and Mars, all together. Image and Caption Credit: NASA/JPL-Caltech/SSI

For nearly 10 years NASA’s Cassini spacecraft has been delivering a wealth of valuable science about Saturn, exploring the [...]

NASA's GRAIL Mission Puts a New Face on the Moon

Scientists, using data from the lunar-orbiting twins of NASA’s Gravity Recovery and Interior Laboratory (GRAIL) mission, are gaining new insight into how the face of the Moon received its rugged good [...]

Carbon Worlds May Be Waterless, Finds NASA Study

This artist’s concept illustrates the fate of two different planets: the one on the left is similar to Earth, made up largely of silicate-based rocks with oceans coating its surface. The one on the right is rich in carbon — and dry. Chances are low that life as we know it, which requires liquid [...]

NASA Rover Confirms Mars Origin of Some Meteorites

This self-portrait of NASA’s Mars rover Curiosity combines 66 exposures taken by the rover’s Mars Hand Lens Imager (MAHLI) during the 177th Martian day, or sol, of Curiosity’s work on Mars (Feb. 3, 2013). Image credit: NASA/JPL-Caltech/MSSS

Examination of the Martian atmosphere by NASA’s Curiosity Mars rover confirms that some meteorites that have dropped [...]

Comet ISON Appears In Tact As it Plunges Toward Perihelion Next Month

NASA’s Hubble Space Telescope captured this image of Comet ISON on Oct. 9, 2013. The image suggests that the comet is intact, a good sign that it will survive perihelion next month when it dives to within one million miles of the Sun’s surface.

On Aug. 5, 2011, United Launch Alliance sent NASA’s JUNO spacecraft on a five-year trip to visit our Solar System’s largest planet—Jupiter. Problem is, Jupiter is so far, and the 8,000-pound solar-powered JUNO is so heavy, that [...]

NASA's Comet-Chasing Deep Impact Mission Is No More
